Hallucinations and Delusions are both symptoms of schizophrenia, which is a sure indication of a misplaced perception of what reality is. Although both words are used to mean the same thing, they differ in meaning and in processes that lead to their occurrence Hallucinations occur as a result of fatigue, stress, drugs, or mental weaknesses, which causes the brain to remember some thoughts and perceptions already stored. Therefore hallucinations occur at conscious periods.

Delusion, on the other hand, is a usual display of multiple personalities at the same time, which causes swings in behavior and disorders. It also means a strong conviction in the unimaginable or impossible regardless of real proofs that disapprove those conceived imaginations of the Unreal and impossible. Both hallucinations and delusions are an end result of deep stress, depression, and severe anxiety. There are medications used in tackling hallucination when it has stayed for on a long term basis.

Delusion and hallucination are different terms. Many of us often use them interchangeably but they do not mean the same thing. Delusion refers to a false belief that is resistant to confrontation with actual facts. Examples of delusions include Delusions of perception (paranoia), the delusion of grandeur, the delusion of control and delusion of reference. On the other hand, hallucination refers to the sensory perception of something that does not exist. It often arises as a result of a disorder of the nervous system.

These perceptions only exist in the mind of the person. Hallucination can be present in any sensory modality such as auditory, visual, tactile, gustatory or olfactory. Examples include A crawling feeling on the skin, hearing voices, hearing sounds that cannot be traced or smelling a strange odor that cannot be explained. Hope you find this useful.

The main difference between a delusion and a hallucination is that a delusion is a fixed yet false belief that which is often perpetuated by deception. A hallucination is a faulty perception in the absence of any external stimuli. These two different diagnoses may arise as a result of psychosis or some mental disorder. Hallucinations are also sensory experiences that are generated by the mind of someone who is sick.

These external stimuli may be seen, heard, felt, and even sometimes smelled or tasted. Generally, when someone is delusional, the belief is not one that is accepted by a civilized society. However, it is not an article of religious faith. When someone is experiencing delusions, they may also have conversations with those who occupy the person's mind.

Before you know the difference between the two, it should be said that delusions and hallucinations are often very real to the person who is experiencing them. A hallucination often involves the use of different senses. For example, a person who is very hungry may hallucinate that there is food nearby.

The person may even smell the food even if there is no food for miles. Someone who is delusional is someone who refuses to accept that something is real even if there are already pieces of evidence that prove that the person’s belief is wrong. For example, a person may say that a person is in love with him even if the person he is in love with has already moved on.
